Helping a child or grandchild buy their first home is something many families want to do, but the right approach will depend on your finances, their affordability and how much support is actually needed.
In some cases, a deposit boost is enough. In others, the challenge is not the deposit but how much they can borrow. The key is to look at the numbers carefully before committing to any one route. Lenders will assess income, spending, deposit source and overall affordability, so it makes sense to start with a clear plan rather than jump straight to a product.
Start with Budgeting, Affordability and a Clear Plan
Before offering financial help, it is worth sitting down together and working through what is genuinely affordable.
That means looking at property prices in the area, likely monthly mortgage payments, other buying costs and how sustainable the budget would be once they own the property. Family support can be valuable, but it should sit alongside a realistic plan for repayments and ongoing bills, not replace one.
Can a Lifetime ISA Help Build a First-Time Buyer Deposit?
For some first-time buyers, a Lifetime ISA can be a useful way to build a deposit more quickly.
A Lifetime ISA can be opened by someone aged 18 to 39. They can pay in up to £4,000 each tax year and receive a 25% government bonus, up to £1,000 a year. The money can be used towards a first home costing up to £450,000, provided the buyer intends to live in it.
So if your child or grandchild is eligible, helping them maximise that allowance can be a simple and tax-efficient place to start.
Should You Gift a Deposit to Help Your Child Buy a Home?
Gifting a deposit is one of the most direct ways to help.
A larger deposit can reduce the loan to value and may improve the mortgage options available. But it is important to remember that gifted deposits usually need to be evidenced during the application, and larger gifts may also have inheritance tax implications depending on timing and wider estate planning.
That does not mean gifting is a bad idea. It just means it should be done with eyes open and, where appropriate, with tax advice.
Can Savings Be Used to Support a Mortgage Without Gifting the Money Away?
Yes, in some cases.
Offset-style arrangements can link savings to a mortgage so that less interest is charged on the loan, while the savings themselves remain in place. Depending on the lender and product, family-assisted structures can sometimes work in a similar spirit, helping with affordability or risk without the money being handed over permanently on day one.
This can appeal to families who want to help but would prefer to retain access to their capital.
Are There Mortgage Options That Let Family Help with Affordability?
Potentially, yes.
Depending on the lender and the family’s circumstances, there may be mortgage structures that allow a parent or grandparent to support the application. That can include guarantor-style support or, in some cases, intergenerational arrangements such as joint borrower sole proprietor mortgages. These are not right for everyone, and they can create shared liability or longer-term complications if not set up carefully.
The right route will depend on whether the issue is deposit, affordability or both.
Is Equity Release Ever an Option for Helping Children Buy a Home?
For some older homeowners, equity release may be part of the conversation.
Equity release allows money to be released from a home while continuing to live there, with repayment typically happening later when the property is sold after death or a move into long-term care. It can be useful in some circumstances, but it is a major decision with long-term consequences for interest costs, inheritance planning and future flexibility.
Because of that, it is usually something to consider carefully rather than treat as a quick fix.
What Should Parents and Grandparents Consider Before Helping?
The main question is not just how you can help, but whether the help is sustainable and sensible for your own position.
Any support should be weighed against your retirement plans, emergency savings, future borrowing needs and the level of risk you are comfortable taking on. It is also worth being clear from the outset whether the money is a gift, a loan or part of a wider family arrangement, as that can avoid misunderstandings later.
